Experimental methods in chemical engineering: Fluorescence emission spectroscopy

“…at (Figure ). The linear portion of the curve (insert of (Figure ) decreases 15 units every . This phenomenon is attributable to heat‐facilitated non‐radiative deactivation processes …”

Reducing Temperature Calibration Error in Multivariate Analysis of Fluorescence Spectra

“…Currently there are several types of fluorescent sensors for temperature calibration. They can be based on the active medium fluorescence band shift [1], fluorescence decay time change [2] and fluorescence intensity change [3] or fluorescence intensities ratio from two thermally-coupled energy levels [4] or noncoupled levels of doping ions [5], respectively. From the fluorescence spectra, only measurements at a small number of wavelengths are usually used to calibrate the temperature.…”

Dual‐activator luminescence of LuAG:Mn4+/Tb3+ phosphor for optical thermometry

“…Besides, it can be employed to harsh environments such as those with strong electric fields and/or strong corrosiveness, and also can be adapted to small‐scale measurements like those in tiny electronic components and microbial cells . The mechanism of optical temperature sensing is based on some temperature‐sensitive parameters of luminescent materials, such as the fluorescence lifetime, spectral position, fluorescence absolute intensity, fluorescence intensity ratio (FIR), emission band shape, and persistent luminescence, which can be designed into useful techniques to calibrate temperature. Among those techniques, optical thermometry based on FIR is not influenced by the fluctuation of excitation power thus has higher stability, making FIR‐based strategy a more precise and promising detection mode.…”
